Application filed March 22, 1906. Serial No. 307,436.

To all whom it may concern:

Be it known that I, JAMEs W. Hrcxs, a citizen of the United States ,residing at Everson, in the county of Fayette, State of Pennsylvania, have invented certain new and useiul Improvements in Switch-Signals; and I do hereby declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to signals, and more articularly to railway-switch signals, and lias for its object to provide a signal-lamp for switches which will be so arranged that it may be filled and otherwise tended from the ground without the necessity of climbing the supporting-pole of the lamp.

Another object is toprovide a lamp embodying these features which will .be arranged to swing so that it may maintain an upright position when lowered and which will be provided with means for shifting it to indicate the condition of the switch when the latter is thrown;

Other objects and advantages will be apparent from the following description:

In the drawings forming a portion of this specification, and in which like numerals of referenceindicate similar parts in the several views, Figure 1 is an elevational view of the signal with the lamp in raised position. Fig; 2'is a view similar to Fig. 1, showing thelamp lowered. Fig. 3 is an enlarged vertical section of the rod, showing its connection with theupright and with the shifting mechanism. Fig. 4 is a horizontal section on line 4 4 of Fig.

. 1, showing the shifting mechanism in top lan. Fig. 5 is an enlarged detail view of the amp, a portion of the latter being broken awayto show the engagement of a bar therein.

Referring now to the drawings, the present invention comprises an upright 5, having a plurality of divergent supporting-legs 6, to

which there is secured a horizontal plate 7, this plate being thus located within the inclosure of the legs. The upper end of the upright 5 is turned laterally at right angles, as shown at 8, and is cylindrical, as shown, for introduction into a circular collar 9 ,which extends laterally from the vertical sleeve 10. This sleeve is engaged with the reduced central portion 11 of a rod 12, and the reduced portion 11 is somewhat longer than the sleeve 10, so as to permit of both sliding and rotary movement of the rod in the sleeve. By reason of the engagement of the end 8 of the upright in the collar 9 the sleeve and rod are movable pivotally in a vertical plane with respect to the upright, and set-screws 13 are engaged in the collar and extend into a circumscrlbing groove 14, formed in the laterally-turned end of the uprightto prevent disengagement of thecollarfrom this end, and

it will be understood that the set-screws may be operatedto impinge against'the an ular end of the upright, thus holding the s eeve and rod stationary with respect to the upright. A set-screw 15 is engaged in the sleeve 10 for operation to hold the rod against 7 movement therein.

A yoke 16 is carried by the upper end of the rod and has a signal lam 17 mounted between its vertically-exten ing arm 16 for sw nging movement'upon a horizontal axis. Th s lamp 1s arranged to display two colors,

as shown at 18 and-19, as is usual, and, as

will be seen, the rod 12 maybe revolved in the sleeve 10 to give the desired signal to trainsw upon the track. The rod 12 has a longitunally-extending passage 20 formed there through which is angular in cross-section, and. slidab y engaged in this assage and project ing beyond the ends of the rod there is a cross-sectionally angular bar 21. This bar at its upper end extends into an o ening 22 in the bottom of the lamp 17, whic holds the lamp against pivotal movement in the yoke,

and at its lower end the bar 21 lies normally within an angular socket 23, formed in the upper end of a socket piece 24, which is revolubly mounted for vertical position in the plate 7. A laterally-extending lever 25 is carried by the socket-piece 24 and is connected by means ofa link 26 with the switchthrowing mechanism 27 of a track 28. As

will be seen, the arrangement is thus such that when the switch is thrown the position of the lamp 16 will be changed and the signal thus altered to indicate the position of the switch. Diametrically opposite longitudinal recesses 29 are formed in the inner surface of the rod 12 and laterally-extending lugs 30,

carried bythe bar 21, extend into these recesses, the longitudinal movement of the bar;1 with respect to the rod being thus limite i As will be apparent from the drawings, the arrangement is thus such that the rod 12 may be raised with respect to the sleeve 10 and for i v a certain distance with respect to the bar 21 this movement of the rod with respect tothe bar being sufficient to bring the bar out of en- IIO ement with the lamp 17, so that the latter ee to move upon its pivot. Further vertical movement of the rod will bring the lower end of the recesses 29 into engagement with the lugs 30, and the bar 21 may then be raised, with the rod, to bring the lower end of the bar out of the socket 23, thus permitting movement of the sleeve revolubly upon the laterally-turned end of the upright 5, so that the upper end of the rod 12, with the lamp, may be lowered, the pivotal mounting ofthe lamp permitting it to maintain an upright position during this downward movement. The'method of returning the lamp to its operative position will be readily understood without further description, and it will be understood that the rod may be held against movement to lower the lamp by the set-screws 13, as described above.

What is claimed is 1. A signal comprising a support, a vertical rod pivoted upon the support, a signaling device carried by the upper end of the rod, said rod being movable to bring the signaling device within reach of the ground, said rod bein movable to shift the signaling device into different signaling positions, and means engaged' with the lower end of the rod for shifting the rod,said rod being movable slidably out of engagement with the shifting means to permit of downward movement of the upper end of the rod.

2. A signal comprising a support, a vertical rod pivoted upon the support for downward movement of its upper end, a lamp pivotally mounted upon the upper end of the rod for movement upon ahorizontal axis to maintain avertical position at all times, and means for holding the lamp against movement with respect to the rod when the latter is in vertical position, said rod being movable to bring the holding means out of operative position.

3. A signal comprising a support, a vertical member pivoted upon the support for movement of its upper end toward the ground, a lamp pivotally mounted upon the upper end of the member for swinging movement upon a horizontal axis, said rod having a cross-sectionally-angular passage formed longitudinally therethrough, a revoluble socket- )iece mounted vertically at the lower end oi the rod, abar fitted within the passage of the rod for sliding movement therewithin, said bar being engaged at its upper end in the lamp and at its lower end in the socket-piece for rotation of itself and the rod with the socketpiece, and means for rotating the socket piece, said rod being movable vertically independently of the bar to bring the latter out of engagement with the lamp, said bar being constructed and arranged for subsequent vertical movement with the rod to bring the bar out of engagement with the -socket-piece.

In testimony whereof I ilfllX my signature in presence of two witnesses.
